Plain-English summary
A group of 15 cats with an eyeworm infection were treated with a spot-on medication called Broadline to see if it would eliminate the parasites. After just one treatment, all eight cats that received Broadline were free of the eyeworms by Day 14, while the untreated cats remained infected and showed ongoing eye problems. The treated cats also showed improvement in their eye inflammation symptoms. This study suggests that Broadline is highly effective against the eyeworm Thelazia callipaeda in cats.

Abstract
BACKGROUND: The present clinical field trial was conducted to assess the efficacy of a broad-spectrum parasiticide spot-on formulation containing eprinomectin (Broadline) against Thelazia callipaeda eyeworm in naturally infected cats. METHODS: Fifteen privately owned cats harboring at least one live adult T. callipaeda were included in the study. Cats were randomly allocated to an untreated control group of seven cats or to a Broadline-treated group of eight cats. Cats were treated on Day 0; ocular examinations were performed at inclusion and on Days 7 and 14; eyeworms were recovered and counted on Day 14. The primary efficacy assessment was based on group comparison of number of T. callipaeda on Day 14. RESULTS: Seven days after treatment, six of eight treated cats were negative for eyeworm infection per visual examination, and on Day 14 no eyeworms were found in the treated cats while the seven untreated cats were still infected (geometric mean: 1.97). All cats had inflammatory ocular signs at inclusion; on Day 14, five of eight treated cats had recovered while all untreated control cats were still symptomatic. All collected parasites were confirmed to be T. callipaeda by morphology and molecular characterization. CONCLUSIONS: A single treatment with Broadlineprovided 100% efficacy against feline thelaziosis and improved related ocular inflammation signs.
